About Us

Over the past 15 years, we saw every company become a fintech company and we believe that in the next decade - every company will transform into a stablecoin company. At HIFI, we are on a mission to create the tools to power the next chapter of the internet to allow fintechs and enterprises to create entirely new money movement experiences with stablecoins. We move billions across every corner of the world from the U.S., Latam, Africa, and APAC - while working with ambitious startups to reimagine new financial applications and established Fortune 500s.

We are a team of builders, operators, and problem solvers based in the heart of the financial services capital: New York City. Our team is deeply focused on shipping world-class tech products and is rooted in a strong sense of business acumen to create global financial products (Uber, Square, Coinbase, Citi, PWC, Quadpay). We are backed by world-class investors, including Fabric VC, Elevate Growth Fund, Side Door Ventures, and more.

The Role

As a Senior Staff Engineer at HIFI, you’ll be a core part of the team scaling the infrastructure behind our global money movement platform. You’ll lead the design and build of backend systems that help businesses move money safely, reliably, and in compliance with global regulations. Your work will span across systems architecture, infrastructure, and core product engineering.

You’ll partner with Engineering, Product, and Compliance teams to deliver features that directly impact how companies onboard, transact, and stay compliant. You’ll also interface with external partners-from global banks to regulators-to ensure our systems meet the highest standards of performance and trust. This is a deeply technical role with real-world consequences. The systems you build will power stablecoin rails, orchestrate bank settlements, and serve as the foundation for how financial institutions interact with HIFI.

Key Responsibilities:

• Collaborate closely with the engineering team to deliver major product features and expand integrations with new liquidity providers, BaaS partners, and compliance tools.
• Implement and optimize backend services using Node.js and PostgreSQL, ensuring high performance and responsiveness.
• Manage and refine CI/CD processes to enhance development operations and automate deployment workflows.
• Take ownership of specific infrastructure improvements, such as server scaling and event queue management, seamlessly integrating these tasks within the context of broader feature development.
• Build and maintain robust payment flows, ensuring seamless processing and integration with banking and financial systems.
• Work with both internal stakeholders and external partners to drive product requirements, define timelines, and deliver solutions that meet business goals.
• Contribute to the end-to-end lifecycle of feature development from concept through deployment and support.

Required Skills and Experience:

• Proven track record in backend development, with a portfolio of large-scale projects successfully delivered.
• Strong technical proficiency in Node.js and PostgreSQL.
• Significant experience with CI/CD pipeline setup, management, and optimization.
• Experience with infrastructure-related tasks such as server scaling and event queue management.
• Familiarity with building payment flows and integrating with bank systems and cryptocurrency exchanges.
• Excellent communication skills, capable of clearly articulating product, infrastructure, and deployment requirements and impacts.

Desirable Qualities:

• A proactive and independent problem solver who can manage both detailed technical challenges and high-level architectural decisions.
• The ability to balance multiple projects simultaneously, maintaining focus on both infrastructure improvements and feature development.
• Strong analytical skills with the capacity to foresee and manage potential scalability issues in a growing financial technology environment.

We have no hard roles about in-person work, however most of our company works together in our Flatiron office and recognizes it allows us to move faster.

At HIFI, we are focused on building a diverse and inclusive team. While you may not meet all of our requirements, we’d encourage you to apply if you meet the majority of our expectations. You may be a great fit for this role or another role in our team.
